ATTORNEYS FLEXIBLE PLASTIC DRAWER-TYPE RECEPTACLE GUIDE BACKGROUND OF THE INVENTION The invention pertains to the art of guides and slides for drawer members and the like wherein relative longitudinal movement between the drawer and its supporting structure occurs.

In the drawer guide art it has been common practice to use channel-shaped members, tongue and groove arrangements, rollers, ball bearing devices, and other types of bearing systems which permit a sliding movement of the drawer, or similar element, relative to its support. Depending upon the desired characteristics of the support, one of the above known types of bearing members is utilized. Where the drawer is to be freely movable, yet may be rather heavily loaded, it is common practice to use ball guide members having antifriction characteristics.

More recently, various types of synthetic plastic guides have become available for use with particular applications, and such guides are known to use flexible components. The state of the prior art is represented by U.S. Pat. Nos. 2,835,539; 3,032,377; 3,059,986; 3,126,230 and 3,321,253.

In certain applications, such as supporting a drawer-type ash receptacle mounted upon the dashboard of an automobile, it is desirable to support the receptacle rather firmly whereby the vibration of the vehicle does not cause a rattling" of the drawer, nor permit the drawer to vibrate and inadvertently move relative to its support. Another important requirement for ash receptacles of this type is that they comply with the 1966 Motor Vehicle Safety Act in that the receptacle must be able to break away" in the event it is struck, when in the extended position, by a vehicle occupant during a collision. Under these circumstances the receptacle must be able to be displaced from its supporting member upon application of a predetermined force transverse to the nonnal path of receptacle movement.

Prior art devices which have endeavored to meet the above requirements are expensive and often inconsistent in operation, and assembly techniques often are unduly c'omplex.

SUMMARY OF THE INVENTION It is an object of the invention to provide a glide arrangement for drawer type receptacles, particularly of the type which can be used with automobile ash receivers and the like, which is economical to manufacture and assemble to the associated components; which will support the receptacle firmly to prevent vibration and noise, yet permits the receptacle to easily slide in its-desired path of movement; and which will permit the receptacle to break away" from its support member in the event it is struck by an impact of predetermined force in a direction transverse to the normal path of movement.

In the practice of the invention the drawer member includes parallel spaced sidewalls having outwardly extending elongated protuberances defined thereon. The protuberances are of a configuration which corresponds to the desired path of movement of the drawer as it is moved between open and closed positions. The drawer-supporting member supports a pair of guide elements formed of synthetic plastic material which are of an elongated configuration complimentary to that of the protuberances. The guide elements are of a generally U or channel-shaped configuration including a base region and leg portions or extensions depending from a lateral side of the base region. The leg portions extend toward the drawer, and engage the drawer adjacent the base of the protuberance, and the protuberance is received between the leg portions.

The leg portions are of a firmly flexible nature as to impose a limited biasing force upon the drawer. In that the guide elements exert opposed biasingforces upon the drawer the drawer will be centered between the guide elements, yet is firmly supported as to resist vibrations and inadvertent movement due to vibration. The leg portions include outer end regions which are of arcuate configuration depending away from each other to facilitate the flexible engagement with the drawer, and to improve the characteristics of the engagement between the guide element and the drawer sidewalls and protuberance base.

As previously mentioned, it is desired that the support of the guide element of the drawer be such as to permit the drawer to break away from the guide member under certain conditions. This characteristic is achieved by the shaping of the protuberance and the leg portions of the guide members, in conjunction with the firm, yet flexible, characteristics of the leg portions. Thus, upon a predetermined lateral force being imposed upon the drawer, the leg portions are able to deflect sufficiently in a direction transverse to their longitudinal length to permit the drawer to be displaced from its supporting guide element in a direction transverse to the normal operating path of movement of the drawer.

Preferably, the guide elements are formed of a synthetic plastic material such as acetal resin, which has self-lubricating characteristics, as well as a flexible resilient nature, which facilitates the operating movement of the drawer.

' The guide member of the invention is self-adjusting with respect to the tension required to move the drawer and equal pressure will be imposed on the drawer by each guide element while the drawer is being moved, which minimizes sticking and binding and assures a smooth operating motion.

The practice of the invention minimizes the component parts required with an automobile ash receiver, for instance, yet permits the ash received to be opened to a greater extent than prior art types of ash receptacle supports. Additionally, the assembling techniques when using the practice of the invention are simplified and the entire construction is more economical than those previous constructions for vehicle ash receptacles.

DESCRIPTION OF THE PREFERRED EMBODIMENT It is to be appreciated that the inventive concept is directed to a guide arrangement for slidable devices such as drawers and the like, but may be used in a wide variety of applications. In particular, the invention is useful in conjunction with sliding drawer-type receptacles formed of sheet metal and the like, such as ash receptacles used in automobiles, and, for purposes of illustration, the inventive concept will be described in this context.

FIG. 1 illustrates a typical ash receptacle environment utilizing the concept of the invention. The ash receptacle is supported within a supporting member generally identified at 10 which would usually be formed of sheet metal and includes an upper panel 23 from which downwardly depend side supporting member walls 14. These walls may be oflset adjacent the panel 12, if desired. The panel 12 is recessed at 16 and is provided with a lanced projection 18 for selective cooperation with the drawer receptacle stop mechanism, as will be later described.

A plurality of holes 20, FIG. 2, are defined upon the supporting member walls 14 for receiving the mounting rivet projections of the guide element in accord with the invention, and these holes are defined in an arcuate path to correspond with the drawer guide elements and protuberances as will be later apparent.

The ash receptacle is in the form of a drawer 21 having a bottom panel 22 to which are welded parallel sidewalls 24 by means of flanges formed on the sidewalls. A rear panel 26, FIG. 2, is formed by bending upwardly the rear portion of the bottom wall 22 which is attached to flanges on the rear of the sidewalls. The front wall of the receptacle is defined by an upwardly extending oblique portion 28 of the bottom panel, and an outer cover plate 30 attached to the front wall 28 by means of fasteners, not shown, which extend through the lower region of the cover and pass through the bottom panel 22.

The sidewalls 24 are formed with snuffing lands 32, and a cantilever supported arm 34 extends from the upper flange 36 of the rear panel 26 toward the front wall 28, and includes an abutment 38 adapted to interfere with the lanced stop 18 and limit outward movement of the drawer relative to the support 10. The arm 34 may be depressed by pushing down on the portion 40 to misalign the abutment stop 38 with the lanced stop 18 and thereby pennit complete withdrawal of the drawer 21 from the support when it is desired to empty the contents of the ash receptacle.

The sidewalls 24 are each formed with an elongated rib or protuberance 42 defined by displacing the metal of the sidewalls outwardly with respect to the general drawer configuration. The protuberances 42 are of a configuration corresponding to the path of movement that the drawer will take when being moved between the open and closed positions. In the disclosed embodiment the protuberances are slightly curved with respect to their longitudinal direction, but these protuberances may be linear, if desired.

The protuberances 42 have a transverse cross-sectional configuration as will be apparent from FIG. 3. This configuration is of a somewhat semicylindrical shape whereby the protuberance defines an apex at 44, and base surfaces at 46, which are of a concave configuration where the protuberance blends into the plane of the outer sidewall surface 48. It will be noted that as the base surfaces 46 are of a concave configuration and blend tangentially into the convex configuration of the protuberance toward the apex so that the outer configuration of the'protuberances, with respect to the transverse cross section, is free of shoulders, sharp angles, and the like, and is of a relatively smooth and rounded shape.

The drawer receptacle 21 is supported upon a pair of guide elements 50 affixed to the support walls 14. The guide elements are preferably formed of a synthetic plastic material such as acetal resin, which has self-lubricating qualities, and are of a configuration complimentary to the longitudinal configuration of the protuberances 42 having a generally U or channel cross-sectional configuration as will be appreciated from FIGS. 2 and 3. The elements 50 include the base region 52 which has an outer base surface 54 and an inner planar surface 56. The base region 52 includes lateral sides at 58 from which depend leg portions or extensions 60 transversely disposed to the plane of the element surface 54. The leg portions 60 are arcuately formed at 62 whereby the free end regions of the leg portions depend away from each other and the outermost end surfaces 64 of the end regions engage the drawer sidewall surfaces 48 adjacent the protuberance base.

The elements 50 are maintained upon the supporting member sidewalls 14 by rivet projections 66 which extend through the holes defined in the walls, and these rivets may be headed" by a heat tool to form a head as will be apparent in FIG. 2. In this manner the elements 50 are firmly attached to the support 10.

As will be appreciated from FIG. 2, the elements 50 are located in opposed relationship to each other and the assembled components are as shown in FIG. 2. The spacing between the supporting walls 14 and the sidewalls 24 of the drawer 21 are such that the relationship between the protuberances 42 and the guide elements 50 will be such as shown in FIG. 3. In this relationship the protuberance apex 44 is substantially engaging the element surface 54, and the element leg portions 60 are engaging the sidewalls 24 at the protuberance base surfaces 46. The spacing of the drawer sidewalls 24 is such that a slight deflection of the leg portions 60 occurs in the assembled relationship wherein the leg portions maintain a biasing force on the drawer away from the associated guide element. In this manner the guide elements 50 maintain the drawer 21 centered between the supporting walls 14, and also impart a frictional interconnection between the guide elements and the drawer sidewalls. Additionally, the engagement between the protuberance apex 44 and the surface 54 aids in centering the drawer between the walls.

In that the leg portions 60 are formed of a flexible material, yet a material which is rather firmly resistant to flexing, the lower leg portions 60 serve to support the weight of the drawer, and the drawer may be slid between the open position shown in FIG. 1, and a closed position whereby the cover 30 is disposed adjacent the wall flanges 68. Because of the biasing force maintained upon the drawer by the leg portions 60 no metal to metal" contact exists between the drawer 21 and the support 10 and looseness" and other relationships which would be noticeable when subjected to vibration are eliminated. The rather firm interconnection between the drawer and the support prevents rattling of the drawer, and the receptacle will remain quiet" during movement of the vehicle, and also when sliding between its open and closed positions.

Should the drawer receptacle be located in its open position, as shown in FIG. 1, when the vehicle is engaged in a collision, and is struck by a portion of the occupant's body, the leg portions 60 are able to deflect sufficiently to permit the drawer 21 to be laterally pushed from the guide elements 50 due to the flexing of the leg portions 60. This breaking away" of the receptacle from the support member is also facilitated by the smooth convex contour of the protuberances 42. However, the firmness of the leg portions is such as to prevent accidental release of the drawer from the drawer guide during operation or casual bumping" of the receptacle and the thickness, length, and other physical characteristics of the leg portions 60 are so determined that release of the drawer only occurs upon a predetermined force being applied to the drawer in a direction transverse to the length of the protuberances and guide elements.

It is to be appreciated that the guide elements 50 could be mounted upon the sidewalls 24 of the drawer, and the protuberances 42 formed in the walls 14 of the support member, and still utilize the practice of the invention.

FIGS. 4 through 8 are directed to a variation in the practice of the invention wherein a built-in" for the drawer relative to its supporting member is provided, the stop structure being incorporated into the protuberance and guide elements.

With respect to FIG. 4 the support member 70 includes sidewalls 72, and it will be appreciated that the structure of the supporting member is similar to that shown in FIG. 1 except for the presence of the stop structure 16 and 18. Guide elements 74 are affixed to the inner surfaces of the support member sidewalls 72 by the rivet projections 76 defined on the guide elements and inserted through holes defined in the support member sidewalls.

The drawer element of FIG. 4 is identical to that shown in FIG. 1, and similar components are indicated by primes. However, the stop mechanism 34, 38 and 40 is not present in the drawer 21'.

As will be appreciated from FIGS. 5 and 7, the protuberances 42 defined upon the drawer sidewalls 24' do not have the rounded apex 44 of the protuberances of the previously described embodiment, but rather the protuberances include a rather flat portion 78 which terminates short of the base regions 52 of the guide element 74. Similar components of the protuberance and guide elements of the embodiment of FIGS.

4 through 8 are indicated with prime reference numbers to those previously described.

At least one, and preferably both, of the protuberances 42' defined on the drawer sidewalls 24' are formed with a stop shoulder 80, FIGS. 6 and 8, on the flattened apex portion 78. The stop shoulder 80 includes an oblique backing surface 82, and is defined by deforming a portion of the associated protuberance from its general configuration without the fracturing of the material of the drawer sidewall.

At least one of the guide elements 74, and preferably both, are formed with an abutment shoulder 84 defined homogeneously from a material of the associated guide element extending from the base region 52. The abutment shoulder 84 is disposed at an oblique angle with respect to the length of the guide element and its projection toward the associated protrusion portion 78 places the abutment shoulder within the path of movement of the stop shoulder 80 of the associated protuberance. Thus, with respect to FIG. 6, as the drawer moves to the right with respect to the guide element 74 the stop shoulder 80 will engage the abutment shoulder 84 and limit withdrawal of the drawer 21' from its support member 70. However, should the operator desire to completely remove the drawer from the support member 21' to permit emptying of the drawer, it is only necessary to pull harder upon the drawer causing the stop shoulder 80 to ride up and over the abutment shoulder surface 84, FIG. 8, and thereby clear the abutment shoulder. This operation is permitted by the deformation of the support sidewalls 72, and as previously mentioned, this deformation, plus the ability of the guide element portions 60' to deform permits the drawer 21 to be released from the support member under emergency conditions when struck with a transversely directed impact.

Once the drawer 21' has been removed from the support member 70 it may be easily reinserted, with little force, in that the rather gently inclined protrusion cam surface 82 will engage the inclined guide element surface 86 to permit the stop shoulder 90 to again ride over the abutment shoulder 84 that the stop shoulder and abutment shoulder may assume the desired position for limiting normal withdrawal of the drawer with respect to the support member.

The embodiment of FIGS. 4 through 8 substantially reduces the cost of the construction as compared with the embodiment shown in FIG. 1 through 3 and provides a greater access opening in the drawer in that it eliminates the element 40 from the central region of the drawer opening.
